Influence of harvesting season and post harvest storage time on carotenoid biosynthesis in Malaysian orange sweet potato (ipomoea batatas) tuber flesh

Carotenoid content in plants differs due to several factors such as cultivar, maturity, climatic, geographic effects, and storage. Improving the nutritional values of sweet potato is an important breeding goal and understanding the regulation, genetics and inheritance of carotenoid biosynthesis is v...
